Clarkson-McCarthy inequality on a locally compact group

Dragoljub J. Kečkić, Zlatko Lazović

Let $G$ be a locally compact group, $μ$ its Haar measure, $G^$ its Pontryagin dual and $ν$ the dual measure. For any $A_{θ} \in L^{1} (G; C_{p}) \cap L^{2} (G; C_{p})$ , ($\ma…

The applications of Cauchy-Schwartz inequality for Hilbert modules to elementary operators and i.p.t.i. transformers

Dragoljub J. Kečkić

We apply the inequality $∣ ⟨ x, y ⟩ ∣ \leq ∥ x ∥ ⟨ y, y ⟩^{1/2}$ to give an easy and elementary proof of many operator inequalities for elementary operators…
